This publication discusses a specific ground-signal-signal-ground (GSSG) configuration of a high-speed differential signal pair. Simulations show that frequency resonances occur when a quarter-wavelength resonant structure is unintentionally created, which causes the observed frequency resonances. To remove the resonances, this publication recommends two design methods. Each proposed method has its own benefits and limitations. The proposed solutions may be treated as design rules for similar high-speed differential signal pairs.
